I believe you are right with all of them.
I think it is 22.5, since molly has 75% of the packs
Area= 5(-4-(-1)) + 5(-1-(-1))+1(-1(-4))/2 = 6.00
Okay so basically domain =input and range =output. you can never have a negative number underneath the square root sign because it will make the answer imaginary (i), unless you are on that concept. Therefore the range is any number greater than 0. -> all real numbers greater than or = 0
for the range if you input 0 as x you will get -5, so any number you input after 0 will be greater than -5. so range is all real numbers greater than or equal to -5.
